EDGE-IRONING MACHINE.

Application filed October 29, 1909.

To all whom t may concern Be it known that l, lfViLLIAM A. Znmnnn, a citizen of the United States, and resident of the city, county, and State of New York, have inventedv certain new and useful Improvements in Edge-Honing Machines, of which the followingis a specification.-

rlhe invention has for its object a machine for removing the bur from the edges of laundried articles and giving them a perfectly smooth finish. For this purpose, the collars7 cuffs or other articles, after they have been ironed, are put through the present machine.

In the drawings, which show only one of the forms which my improvements may take, Figure 1 is a side elevation of the machine; Fig. 2 is a top plan view, portions of the parts which project beyond the limits of the drawing being broken away; Fig. 3 is a rear elevation of the machine; Fig. 4 is a vertical section partly in elevation on the line 4 4 in Fig. 2 looking in the direction of the arrows; Fig. 5 is a horizontal section partly in plan on the line 5-5 in Fig. 1 looking in the direction of the arrows; Fig. 6 is a vertical section partly in elevation of one of the moistening wheels and related parts; Fig. 7 is a detail partly in elevation and partly in vertical section of part of the clutch devices for adjusting the belt tightener pulley; Fig. 8 is a vertical section partly in elevation on the line 8&8 in Fig. 2 looking in the direction of the arrows; and Fig. 9 is a vertical section partly in elevation on the line 9-9 in Fig. 5 looking in the direction of the arrows.

Describing now the devices of the drawings and reserving it to the claims to point out the novel features and to indicate the scope of the invention, 1 designates the bed plate of the machine; 2 are posts on opposite sides of the bed plate (see Figs. 1, 2, 3 and 5). The rear of themachine is at'the left in Fig. 1 and the front is at thel right of said figure.

3 is the driving pulley on horizontal drive shaft 4, the latter supported in suitable bearings from the bed plate.

5 is a gear on the drive shaft meshing with gear on the'horizontal shaft 7 which latter carries a pulley 8 located in about central position relative to the sides of the bed plate. This pulley 8 is the drive pulley of the main carrying-belt 9 of the machine.

Serial No. 525,375.

rllhe course of this belt is well shown in Fig. 1. Its lower stretch runs over the belttightening pulley 10, under pulley 11, around roll 12b at the front of the machine, whence the upper' stretch of the belt proceeds rearwardly under pulley 14, thence up over roll 15 and down to the initial or drive pulley. rlhe belt-tightening pulley 10 is adjustable up and down to any suitable eX- tent by special means hereinafter described. The other described pulleys and rolls that guide the carrying belt 9 turn about stationary axes, it being noted that the pulleys are in a central fore and aft zone through the machine. r:[he rolls 12b and 15 have central annular recesses which the belt 9 runs in and is guided by. rlhe roll 15 is on a shaft 16 (compare Fig. 8), the latter being supported by its ends in bearings 17 on the posts 2. rThe pulley 14 turns on an aXle 18 that eX- tends across between the posts 2. 12a is a roll on top of the roll 12b and is contactdriven therefrom. rThe collar, cuff or other article A is entered endwise into the bite between these rolls 12a and 12b and is carried rearwardly resting on top of the belt 9.

19 are a pair of guides, each swinging in a horizontal plane about a vertical aXis 20. rlhe guides are at opposite edges of that portion of the upper stretch of the belt 9 that runs back from the entering rolls 12n and 12". Each guide 19 consists of a spaced apart top and bottom (best shown in the sectional view Fig. 8) secured together along their respective outer edges 21. lThus, the collar or cuff enters between the top and bottom of the guides and at each side bears against the inside or bearing surfaces 22 of the guides. rllhese surfaces 22 converge toward each other as indicated in Fig. 2. Of course, as the collar or other article enters, it forces ,the guides apart to an extent depending upon the width of the article. A spiral spring 23 connects the guides and insures their engagement with the article at all times. At the rear end of each guide 19 is a moistening wheel 24, shown in plan in Fig. 5, in side elevation in Figs. 1 and 4, and in vertical section in Fig. 6. Each wheel turns freely about a vertical supporting pin 25, the latter being supported from a horizontal arm 26 attached to its guide 19. The arrangement is such that as the article leaves the guides 19, the moistening wheels 24 bear against its edges. The wheels are,

of course, caused to rotate by the article as it passes and means is provided for maintaining their peripheral surface moist so that the edges of the article are moistened thereby. Thus, each wheel has a recess 27 in its top communicating by a series of apere tures 28 with the peripheral surface of the Wheel above the place where the wheel contacts with the article A (compare Fig. 6).

29 are water-troughs supported one from each guide 19 and leading the water by a spout 3() into the recess -27 of its wheel. Supports for the troughs consist in each case of an arm 31 having pivotal connection at 32 with its guide 19.

33 are stationary water-delivering nozzles, one dipping into each trough 29 (compare Fig. 1) having control cocks 34 and being connected by pipes 35 with a water tank 36 or `any other source of supply. The wheels 24 may be made of any suitable material for the purpose; for example, the following materials yanswer well:-a hard wood such hickory, unglaZed clay, marble, glass with a ground surface.

The water supply having been regulated by the cocks 34, the water oozing from the apertures 28 keeps the surface` of the wheels moist with a film of water which meistens the edge of the article without over-moisten ing it, that is, without moistening portions of the article back from the edge, which is something to be especially avoided since it spoils the ironing or finish of that part of the article. The succeeding operation is the ironing down and the giving of a perfectly smooth nish to the thus moistened'edges of the article. For this operation, the article is bent or arched so that in ironing said edges much greater force can be applied to the irons without collapsing or crumpling the article, than if the iron be applied to the edges of the article in flat or non-arched position. Tn the latter case, sufficient ironing pressurecannot be applied to give a perfectly smooth edge, whereas the arched treatment of my present invention makes this practical.

Describing now the devices shown, the article A is carrier under and up around the pulley 14. This arches it.

37 are the irons movable to and away from each other and held in yielding engagement with opposite edges of the article. Each iron shown consists of a solid piece of metah having a vertical groove 38 in its inside face to receive, bear against and iron the edge of the article. There is a sliding carriage 39 for each iron, behind which it is supported by a webv 40. Each carriage consists of an open rectangular frame, through the ends of which are openings, which reeeive through them the axle 18, on which the carriages slide. The posts 2 that support this `aide (compare Fig. 5) are located within the rectangular frames of the respective carriages 39.

42 are curved guides, one supported under each carriage 39. The guides curve upwardly at the rear (Figs. 1, 3 and 9) and receive the edges of the article as it bends upwardly or arches in following around the pulley 14.A The front end of each guide 42 is supported by a web 43 from its carriage 39, and its rear end is attached to the corresponding` iron 37. Each guide consists of a top and bottom secured together along their outer edge 44 (see Fig. 9). Thus each guide has an 'internal contact surface 45 against which the advance corner-portion of the article bears. These contact-surfaces 45 of the two guides incline toward each other, so that the entering article gradually pushes the guides farther apart, and simultaneously carry with them the carriages 39 and the irons 37. The upwardly curving exits of these guides 42 lead to the vertical grooves 38 in the irons, and consequently the irons bear directly against opposite edges of the article A as it arches upwardly past the irons, as indicated in Fig. 5.

The irons are yieldingly pressed toward each other and against the respective edges ofthe article by means as follows: 46 are bell-crank levers pivotally supported at 47, one from each post 2. The vertical arm of each lever bears against the carriage 39 on its side to carry it inward toward the article, whereas the horizontal arm carries a weight 48, adjustable by a set-screw thereon to have greater or less leverage to give greater or less ironing pressure against the article as desired. The actual part on each carriage that the described lever 46 bears against is a roller 49 turning on a stud 50 projecting rearwardly from the carriage. Further, it will be noted that the so-called vertical arm of each lever is in fact somewhat inclined and in pressing inwardly, bears up under the roller, and by easing the weight of the carriage on its rear side, makes it slide more easily than it otherwise would do, since the weight of the iron bears the carriage down at the back. As a further means of giving easy running to the carriages in spite of the unbalancing effect of the irons, I provide an arm 51 depending from the bottom of each guide 42 and supporting a roller 52 that runs between tracks 53. (See Figs. 1 and 3.) Under each iron is a heating-burner 54 supported by gas-pipe 55. The moistened edges of the article having been ironed or edged with practically any degree of pressure necessary, said article progresses from its arched position, upwardly until its forward end enters under the secondary belt 5G, which then delivers the article from the machine and may additionally shape it by adjusting it as hereinafter described. The shaping position of this belt is shown in Fig. 1, and 'its merely delivering position in Fig. 4. 57 is a guide insuring the proper feed of the article to this belt 56. The belt runs about two rolls 58 and 59, the former turning about a fixed axis and the latter being supported on a tilting frame. Thus, the roll 58 is fixed on a shaft 60, which is supported by end-bearings 6l on the posts 2. The tilting frame that supports the other roll 59 has side-bars 62 pivotally supported at 63 from the bearings 6l (Fig. l). The rear ends a of these side-bars curve or extend upwardly and are rigidly connected by a cross-rod 64. The front portions of these side-bars are extensible and each consists of a threaded portion b, a sleeve-nut c on the end thereof, said nut having a recessed head. These recesses contain projecting spiral springs (l. Inside each spring and projecting down into said recesses are pins e, which at their upper ends support the bearings f of the shaft 65 of the roll 59. rlhe lower stretch of the belt 56 runs over a roll 66 whose shaft turns in fixed end-bearings 67 supported from the heretofore mentioned bearings 61.

The described tilting frame may be locked in one or other of its positions, Fig. l or Fig. 4. Thus, 68 is an upright lever which can swing in fore and aft direction about a pivot pin 69. A spring 70 gives said lever normal rearward tendency. 0n the back of the lever is a fin 71 having upper and lower recesses 72 (Figs. l and 4), one or the other of which receives the cross-rod 64 of the tilting frame and locks the latter in its different positions Figs. 1 and 4. The driving of the belt 56 is accomplished from a gear 73 on shaft 16 (Figs. l and 3), through an intermediate gear 74 in mesh with a gear 75 on the shaft 60 of roll 58. The purpose of the extensible front arms of the tiltingframe side-bars is to give the requisite tightness or looseness to the belt depending on it-s position Figs. l or 4. When in its shaping position, Fig. l, it shapes the collar A and delivers it into a conical receiver 76 (see dotted lines Fig. 4), whereupon the succeeding collar or collars force out the first named collar laterally until it drops from the larger end of the conical receiver. rlhus the delivery of the shaped articles from the machine is automatic and continuous, the opera-tor simply feeding the articlesbetween the initial rolls 12a and 12b. On the other hand, in the non-shaping position of belt 56, e. g. for cuffs, Fig. 4, a platform 77 having sides 78 is hung on the machine as shown in Fig. 4, by means of a pair of hooks 7 9 projecting rearwardly from the platform and hooking over the shaft of the rolls 66 and thence under the shaft of the roll 58. On this platform, said cuffs pile up flat one on top of the other.

The heretofore mentioned means for adjusting'the belt tightening pulley 10 is as follows: Said pulley 10 rotates on a stud 80 projecting from an arm 81 that swings up and down about the shaft 7. (Figs. 1 and 2). 82 is a post projecting from the bedplate at one side of the pulley 10. 83 is a rod with central aperture 84 (Fig. 7) receiving the post 82, whereby the rod is slid able up and down the post. 85 isa spiral spring connecting the arm 81 with the end of the rod 83 over it. 86 is an operating lever fulcrumed to post 2 at 87 and-having its free end bent to extend under the springsupport-ing end of the rod 83. 88 is a ring receiving through it the opposite end of said rod 83 and being itself adjustably secured to lever 86 by set-screw 89.

The operation is as follows: To throw the machine into operation or to further tighten the belt 9, the handle of lever 86 is pressed down, which lifts the rod 83 up on the post 82, and through the spring 85 pulls the tightening pulley l0 upward, and tightens the belt 9, so that the live pulley 8 drives said belt and consequently the machine. The rod 83 remains self-locked in whatever position it may be adjusted into, because the downward pull of the pulley l0, being only on one end of the rod 83, jams the walls of its aperture 84 against the post 82 with locking effect. @n the other hand, to stop the machine, the operator lifts the handle end of the lever 86, whereupon the ring 88 on its opposite end, depresses the free or nonspring supporting end of the arm 83, releases the j am and causes the rod 83 to slide downward on its post, thereby lowering the pulley 10 and loosening the belt 9, so that it is no longer driven by the live pulley 8.
